One of the best pieces of advice Mickey ever gave us was to go rent a warehouse and build a prototype of a store, and not, you know, just design it, go build 20 of them, then discover it didn’t work,” says Jobs.

This isn’t something Apple did just prior to the launch of the stores, but they’re constantly redeveloping it. I’ve been inside this “store within a warehouse” and it’s pretty impressive. It’s a honest, to-scale store within one of their non-descript buildings that’s a bit of campus.
